ScienceCasts: The 2012 Transit of Venus

It won't happen again until December 2117. On June 5th, 2012, Venus will transit the face of the sun in an event of both historical and observational importance. The best places to watch are in the south Pacific, but travel is not required. The event will also be visible around sunset from the USA.

Incandescent Sun

This video takes SDO images and applies additional processing to enhance the structures visible. While there is no scientific value to this processing, it does result in a beautiful, new way of looking at the sun. The original frames are in the 171 Angstrom wavelength of extreme ultraviolet which shows plasma at around 600,000 Kelvin. The video covers 24 hours of activity on September 25, 2011.

Hinode Witnesses Solar Eclipse

Spectacular images from the Hinode spacecraft show the solar eclipse, which darkened the sky in parts of the Western United States and Southeast Asia yesterday.

Solar Eclipse from Space

While flying at about 240 statute miles above Earth, NASA Astronaut Don Pettit captured the rare solar eclipse as the moon casted its dark shadow across the planet below as it lined up between Earth and the sun.

Mt. St. Helens Timelapse

The 1980 eruption of Mount St. Helens in the state of Washington leveled surrounding forest, blasted away more than1,000 feet of the mountain's summit and claimed 57 human lives.

Landsat satellites have tracked the recovery of the surrounding forest. This video shows a timelapse of the recovery, with annual images from 1979-2011.

Stunning View of Lyrids and Earth at Night

On April 21, the 2012 Lyrid meteor shower peaked in the skies over Earth. While NASA allsky cameras were looking up, astronaut Don Pettit aboard the International Space Station trained his camera on Earth. This video is a composite of 316 still frames from that evening.

ScienceCasts: Solar Eclipse in the USA

A "ring of fire" solar eclipse is coming to the USA on Sunday, May 20, 2012. The Moon will pass in front of the sun, transforming sunbeams across the Pacific side of Earth into fat crescents and thin rings of light. It's the first annular eclipse visible from the contiguous United States in almost 18 years. The event will reveal itself in the shadows. Look on the ground beneath leafy trees for crescent-shaped sunbeams and rings of light. NEVER LOOK DIRECTLY AT THE SUN.

NASA calcula 4.700 asteróides potencialmente perigosos para a Terra

A NASA calcula a existência de 4.700 asteróides potencialmente perigosos para a Terra, indicam os dados da sonda WISE que analisa o cosmos através de raios infra-vermelhos, revelou a agência espacial norte-americana.

A agência explia que as observações da WISE (Wide-field Infrared Survey Explorer) permitiram a melhor avaliação da 'população' de asteróides potencialmente perigosos no sistema solar.

Os asteróides potencialmente perigosos integram um subconjunto maior dos asteróides próximos da Terra.

Aqua MODIS: Science and Beauty

Beautiful images from the MODIS instrument on NASA's Aqua and Terra satellites are used by people all over the world every day. But MODIS is about more than just pretty pictures -- the instrument's contributions to science include a better understanding of the Earth's cloud cover, aerosols, phytoplankton levels, and land cover.

Andromeda Galaxy's Double Nucleus

This zoom dives deep into the nucleus of the neighboring spiral galaxy M31, also known as the Andromeda galaxy. The sequence begins with a backyard constellation view and ends with the new Hubble Space Telescope image that centers on the 100-million-solar-mass black hole at the core of the galaxy and the young blue stars surrounding the black hole. This is the sharpest visible-light image ever made of the nucleus of an external galaxy. Astronomers are trying to understand how apparently young ...

IBEX: Observing the Sun's Horizon

The Interstellar Boundary Explorer, or IBEX, is the first mission designed to map the entire region of the boundary of our Solar System. This region emits no light so, instead, IBEX measures the particles traveling inward from the boundary. IBEX's objective is to discover the nature of the interactions between the solar wind and the interstellar medium at the edge of our Solar System.

Hinode Observes an Active Sun

The X-ray Telescope on the Japanese/NASA mission Hinode has been observing the full sun, nearly continuously, for an extended period. In this movie significant small-scale dynamic events can be observed as well as the slow maturation of many active regions now visible on the solar disk. Hinode is joint JAXA/NASA mission to study the connections of the Sun's surface magnetism, primarily in and around sunspots. NASA's Marshall Space Flight Center in Huntsville, Ala., manages Hinode science ...

Stellar Homicide' Simulation

This computer simulation shows a star being shredded by the gravity of a massive black hole. Some of the stellar debris falls into the black hole and some of it is ejected into space at high speeds. The areas in white are regions of highest density, with progressively redder colors corresponding to lower-density regions. The blue dot pinpoints the black hole's location. The elapsed time corresponds to the amount of time it takes for a sun-like star to be ripped apart by a black hole a million times more massive than the sun
